In order to enable an iCal export link, your account needs to have a key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.

I have read and understood the above.

In conjunction with a having a key associated with your account, to have the possibility of exporting private event information necessitates the creation of a persistent key. This new key is also associated with your account and whilst it is active the data which can be obtained through using this key can be obtained by anyone in possession of the link provided. Due to this reason, it is extremely important that you keep links generated with this key private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately remove it from 'My Profile' under the 'HTTP API' tab and generate a new key before regenerating iCalendar links.

AC/DC performance of a fully printed current switching silicon based transistor

Abstract

We present a novel, large area, fully printed nanoparticulate silicon based transistor which is produced by a simple screen printing process under ambient conditions without the need for post processing steps. It functions as a high voltage unit gain two-way current switch for both direct and alternating current. The uniqueness of our device is its principle of operation, which is distinct from those of conventional transistors which rely on electric field modulation or charge injection. Its mode of operation is based on activated transport of charge through the active silicon layer. In the new transistor, switching is achieved by applying a signal to the base which results in change of the direction of the current from between the collector and base to between the base and emitter. We demonstrate the operation of the device printed on flexible substrates using silver as the conductive layer and highly doped P-type nano-silicon as the active layer. It is further demonstrated that the operation of the transistor is independent of the dominant carrier type in the semiconductor and the nature of the junction between the semiconductor and the three contacts.
